Full marks:
* Theme
* Metroidvania (off-genre things were definitely intentional subversions in line with the theme so
markdown there felt improper)

Less full marks (to be clear, "less full" is literal, not a euphemism. There was no 'category' for this game that gets less than a four from me.
* My enjoyment and perception of the game's execution suffered a bit; at one point I got trapped in an enemy and died. And I seemed to get hit by things and fall off platforms and/or out of the screen sort of...a lot, in a way that didn't feel entirely un-cheap. It also seemed to have a bit of performance at leat on my PC, but this cleared up after restarting.
* Aesthetics weren't mind-blowing, but they worked and had a nice unity and the music was pretty excellently chosen. If this had been in a Black/White jam I could have seen it doing decently on that front.

Overall I think this one's a contender.

Genuinely had fun! First off, any controller-friendly game gets a plus in my book. The movement felt super fluid and it was cool to just wander the map and crush enemies. Your use of the themes was interesting as well. I wished there were some music, it would have really enhanced the experience further. Also, one little nitpick: the stun after getting hit is a bit long to me. Great entry!

Impressive entry! A few cut corners but pretty polished overall. The lose-your-abilities angle was a fun surprise, and I was impressed how it was incorporated into room design.

The simple visual style worked pretty well, except for a few times when it was unclear whether something was a pit of death or a room connection, and a couple rooms where it wasn't clear what was a wall and what wasn't. 

Pretty good level design and a lot of interesting environmental hazards. I mostly enjoyed traversal, but I found some of the backtracking tedious. I didn't particularly enjoy getting back out of the bottom right corner, for example. 

Controls were fine, though I wished I didn't have to use the mouse. Ladder felt slightly glitchy at the top. I'm not a big fan of ladders in general, but it was fine. 

Were the teleporters single use or do they just turn off at the end? 

Ok this one is simply amazing!! The graphics are really nice, and the music choices are great, even if not original sadly. It's super fun tho, I really love how the gameplay flows so nicely, even when I was already completely naked of skills just jumping and shooting was still all I could have asked for. (It  IS the most fun when I had everything tho, that I can't really lie, but I really liked the concept of reversevania and I think you executed it really well here)

Wanna give props to the level design too, the fact it is still completely manageable both with and without power ups is definitelly a hard thing to achieve, but you certainly did it here.
Kinda sad that as far as I've understood most bosses are unfinished aparently, and there simply isn't a final boss, wich is a shame, since I was hyped to have a rematch against doppelganger Zeta, I legit tought the final boss was gonna be him but with all the power ups I sacrificed (I guess that's an idea I'm dropping here if you ever wanna add more stuff)

Only nitpicks I have is that as other people already mentioned, pretty much every enemy is always shooting you off-screen, wich is a little annoying at times. Aside from that there's also some specific rooms with a few blind jumps that are also kind of a nuisance, and the camera is also very iffy when it decides to be, sometimes it felt too slow to follow my char so it got really hard to react to missiles coming from the edge of the screen.
The fact all the teleporters were open from the get go also kinda made me speedrun the game ngl, I'm almost sure I didn't even see every single room, altought I am sure I played throught at least most of them.

Well I guess that's it pretty much, I really love it overall, I don't have any rreeeaaall complaints at the end, from the few entries I played as for the time I'm writing this, it's definitelly a top spot contender honestly. I recorded my run for the sake of it too if you ever wanna see it for anything, but not sure if you would get anything helpful from it tbh.

(Btw, the game page says to not choose the first option when I have to make a choice, but I kinda forgot that at the moment so I still chose it, and that didn't block me out of finishing the game at all)

Finally got around to finishing the game! It took me 3 attempts spread across 2 days to get it done, this game is massive! To be upfront, I'm not a fan of the idea that losing power in a game could be fun and your game didn't prove me wrong, even though I suppose I wasn't losing on many hidden secrets (I wasn't looking for any) I just felt like I had to hassle through longer corridors because I couldn't destroy crates or something. But that's kinda the beauty of jams, where we try things we wouldn't do otherwise, so I'm not judging based on that.

Generally speaking I enjoyed the game, combat was definitely the shining part of the experience. I like various enemy design, even though most of them were just shooting at various directions and moving left and right. There were a few "annoying" cases of turret skipping charging phase and shot me out of the sky, or rocket literally waiting for me to cross the gap, to snipe me into the void, but other than that it was smooth. Environmental hazards were nice and I like each region had something unique. One interesting idea I came up with during playing was maybe tweaking movement logic of those flying cylinder enemies to prioritise going on Y axis before X, so we don't have to short hop in order to hit them all the time, that as kinda obnoxious.

Visuals were very consistent, character looked nice, sounds were okay after you got that fix we talked about. Unfortunately I still don't hear music :'( I wish you went a bit more with backgrounds, maybe added some crosshatching or other lines to fill platforms to make areas even more distinct with the limited palette that you had. There was one place where I couldn't distinguish ladder from platforms around it, somewhere in a section with lasers, that's mainly why I'm suggesting some sort of fill texture for platforms. Oh also magenta lines for moving platform rails was a bit jarring.

Level design is great, not much to say there, amazing job.

tl;dr Great game, fun combat, well done!

WOW!

This would be an amazing achievement for a team effort. let alone a single developer turning out such a complete and well polished entry! love the vector art and the gameplay.. 

Not finished yet, But definitely coming back to it.. 

GREAT ENTRY!

Great idea and execution. The game has considerable content and replayability. Animations are juicy and go well with vfx. Audio could be improved with more bgm and more varied sfx.

Good game!

good animation. well synchronizewd with sound. A very megaman kind of appearence.
Narrative also very nicely executed.
Impressive scale of the game, having a map to follow and all. Congrats! very good.

What I would improve. I would make sure that the sound effects are not too loud. Especially if they are related to short instances, like when you press a button. It can be quite deterring. So I naturally turn my sound down.

other than that, it's good. You can spice it up with some double jumps and combos and things like that.

The animation was nice. The FX for turning and jumping added a lot to it too. I thought I wouldn't like the slight deceleration when you stop moving, but since you can turn instantly and start moving fast, I ended up not even noticing it. The simple tileset I feel was a good choice, it looks simple but complete.

I got past the first boss and died and respawned at the first checkpoint. Not sure if there were others along the way that I missed, but the respawn system felt very oppressive. Especially since the first section of the game is linear, respawning means you go back a long ways.

Combat felt fun. The knockback when the player gets hit is nice. The enemies have are interesting to fight since they can shoot trough projectiles. I literally chuckled when I realized the one enemy could use his little shield. The boss was cool too; jumping is the staple of any good sidescrolling boss fight where the boss isn't a giant background.

Fun game.

Really cool game. Agree with everyone else here that difficulty needs tweaking. I also didn't like how every enemy could shoot through walls, it meant there were a couple times where I got sniped by an enemy that was barely on screen. I really liked the artstyle though, the simplicity makes it really clean and charming.

Wow, this is really awesome! The graphics are simple, but work well. The audio is coherent a feels good. The game feels well polished and reminds me of...mega man 2! The getting rid of upgrades is a cool idea and well implemented here. Got rid of the wall jump, then charge shot, then dash. 

There were a few times where I got stuck trying to jump while standing above a ladder. I also found the game pretty difficult (maybe due to a lack of healing?). 

Great job!

Brooo. This was an incredibly designed game. I could tell you planned everything out just by playing the game. Your interpretation of the themes you chose were spot on and it made for an awesome game. That lower right corner though. I knew that was the area that was going to be the most frustrating. But it was a fun frustration. My gut criticism would be maybe increase rate of health drops, but I don't think thats necessary. My deaths really only occurred in the lower right corner of the map. 

My progression: Top Right Generator (sacrificed dash), Bottom Right (sacrificed wall jumps), and then sacrificed my charge shot. I think this was a decent progression. The run back to the end of the game wasn't as challenging as I thought it would be and I think its was due to this path.
